Abstract

The invention is based on a slatted belt for a slatted belt conveyor, preferably on agricultural machines, with two or more rotating belts, which are connected by rods composed of steel or the like, arranged at intervals from one another and running transversely in relation to the belts, the ends of which rods are enclosed by hoops aligned transversely in relation to the rods, the bevelled ends of which hoops lying on the belt are held by staples driven into the belts which pass through the ends of the hoops. In order to further improve the fixing of the rods by means of the hoops, the staples (16) pass through plates (13) composed of steel or the like located on the rear side of the belt (2), the ends (17) of the staples (16) overlapping the edges of the plates (13) and being carried or curved back to the belt and preferably also being carried back slightly into the belt (2). <IMAGE>

Description

Die Erfindung betrifft ein Stabband nach dem Gattungsbegriff des Anspruchs 1.The invention relates to a bar strip according to the preamble of claim 1.

Ein derartiges Stabband ist aus der EP-A-0 340 514 bekannt. Bei diesem Stabband sind die Enden der Befestigungselemente auf der Rückseite des jeweiligen Bandes so abgewinkelt, daß sie parallel zur Oberfläche des Bandes verlaufend auf der Platte aufliegen. Bei einer derartigen Anordnung besteht jedoch die Gefahr, daß die Enden etwa durch Eindringen von Fremdkörpern hochgebogen werden und sich die Befestigungsstelle so lösen kann.Such a rod band is known from EP-A-0 340 514. In this rod band, the ends of the fastening elements on the back of the respective band are angled so that they lie parallel to the surface of the band on the plate. With such an arrangement, however, there is a risk that the ends may be bent up by the penetration of foreign bodies and the attachment point may become loose.

Aufgrund der Erfindung soll die durch eingetriebene Befestigungselemente sichergestellte Befestigung der Bügel so verbessert werden, daß ein ungewolltes Aufbiegen der Enden der Befestigungselemente verhindert wird.Due to the invention, the fastening of the brackets ensured by driven fastening elements is to be improved in such a way that an undesired bending of the ends of the fastening elements is prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Enden die Ränder der Platten übergreifen, zum Band hin zurückgebogen und geringfügig in das Band zurückgeführt sind.This object is achieved in that the ends overlap the edges of the plates, bent back towards the tape and are slightly returned to the tape.

Diese Ausführung hat den großen Vorteil, daß Fremdkörper die Enden nicht mehr unterfassen können; es ist daher auch ausgeschlossen, daß die Enden hochgebogen werden und daß somit die Befestigung der Bügel gefährdet wird. Eine derartige Anordnung der Befestigungselemente sichert die die Stabbefestigung auch bei größeren Belastungen. Eine Beschädigung des Bandkörpers durch die im Band befindlichen Spitzen tritt dabei nicht ein.This version has the great advantage that foreign bodies can no longer grasp the ends; it is therefore also excluded that the ends are bent up and that the fastening of the bracket is endangered. Such an arrangement of the fasteners secures the rod attachment even with larger loads. The tape body is not damaged by the tips in the tape.

Further details of the invention will be explained with reference to the drawing, in which an embodiment the invention is shown. Show it :

a partial plan view of a bar belt for a bar belt conveyor of an agricultural harvesting machine,
Fig. 2

Fig. 3
a section along the line III - III of Fig. 2nd

Das in Richtung des Pfeiles 1 umlaufende Stabband weist an beiden Rändern zugfeste, biegsame Bänder 2 auf, die durch quer verlaufende Stäbe 3 aus Stahl miteinander verbunden sind. Diese Stäbe dienen der Förderung, zugleich tritt infolge des gegenseitigen Abstandes der Stäbe 3 eine Siebung ein.The bar strip revolving in the direction of arrow 1 has tensile, flexible strips 2 on both edges, which are connected to one another by transverse bars 3 made of steel. These rods are used for promotion, at the same time a screening occurs due to the mutual spacing of the rods 3.

Die Bänder 2 bestehen aus Gummi od. dgl. und haben oben und unten eine Deckschicht aus Gummi und dazwischen paketartig zusammenfasste, gummierte Gewebelagen.The tapes 2 are made of rubber or the like and have a top layer of rubber at the top and bottom and rubberized fabric layers which are combined like a packet in between.

Die aufgrund der Erfindung vorgesehene Befestigung der Stabenden 7 an den Bändern 2 erfolgt durch einen Bügel 8 aus Stahl, der sich quer zum Stab 3 erstreckt. Die Enden 9 des Bügels 8 sind abgew-inkelt und sind an ihrer auf dem Band 2 aufliegenden Seite ballig gestaltet. Die Befestigung der Bügel 8 erfolgt durch aus Stahl bestehemde Krampen 16, die die Enden 9 durchsetzen und ohne Materialwegnahme in die Bänder 2 eingetrieben sind.The attachment of the rod ends 7 to the bands 2, which is provided on the basis of the invention, is carried out by means of a steel bracket 8 which extends transversely to the rod 3. The ends 9 of the bracket 8 are angled and are spherical on their side lying on the band 2. The brackets 8 are fastened by means of steel staples 16 which pass through the ends 9 and are driven into the belts 2 without removing material.

Den Bügeln 8 liegen auf der Innenseite der Bänder 2 befindliche Platten 13 aus Stahl gegenüber, durch die die Abschnitte 23 der Krampen 16 ebenfalls hindurchgeführt sind. Die Enden 17 der Krampen 16 sind abgewinkelt und liegen in rinnenförmigen Vertiefungen der Platte 13, die sich in Richtung der Stäbe 3 erstrecken; diese Enden übergreifen zudem die Ränder der Platte 13 und sind mit ihrem freien auslaufenden Abschnitt in das Band 2 zurückgeführt, wodurch der Formschluss zwischen der Platte 13 und den Enden 17 gesteigert wird.Im übrigen sind die Ränder 14 der Platte 13 gemäss Fig. 2 bogenförmig gestaltet, um die rinnenförmigen Vertiefungen zu schaffen und Einschneidungen der Plattenränder in das Band 2 zu unterbinden.The brackets 8 are located on the inside of the bands 2 plates 13 made of steel, through which the sections 23 of the staples 16 are also passed. The ends 17 of the staples 16 are angled and lie in trough-shaped depressions in the plate 13 which extend in the direction of the rods 3; these ends also overlap the edges of the plate 13 and are led back with their free tapering section into the band 2, whereby the positive fit between the plate 13 and the ends 17 is increased. Otherwise, the edges 14 of the plate 13 are curved as shown in FIG designed to create the trough-shaped depressions and prevent incisions in the plate edges in the band 2.

Wie aus Fig. 2 erkennbar ist, verlaufen die Abschnitte 23 v-förmig in der Weise, dass ihr gegenseitiger Abstand im Bereich der Bügel 8 grösser ist als im Bereich der Platten 13. Dadurch wird dem Umlauf der Bänder 2 Rechnung getragen. Auch die Enden 17 sind mit ihren Abbiegungen in den symmetrisch angeordneten Ebenen angeordnet, die durch die Abschnitt 23 bestimmt sind ( Fig. 2 ). Es sei noch erwähnt, dass die Platte 13 innerhalb einer quer zum Band 2 verlaufenden Lücke 25 zwischen zwei Zähnen 26 an der Innenseite der Bänder 2 angeordnet ist.As can be seen from FIG. 2, the sections 23 run in a V-shape in such a way that their mutual distance in the area of the brackets 8 is greater than in the area of the plates 13. This takes account of the circulation of the belts 2. The ends 17 are also arranged with their bends in the symmetrically arranged planes which are determined by the section 23 (FIG. 2). It should also be mentioned that the plate 13 is arranged within a gap 25 running transversely to the band 2 between two teeth 26 on the inside of the bands 2.
